‘Jim Hartle's Gravity is a gem that offers a novel approach to general relativity pedagogy. It is written for senior level undergraduate physics students, but I expect it will be useful for a broader ...

Gravity is the only major force in the universe that doesn’t fit into our current quantum framework, driving the pursuit of a grand unified theory of physics. The new test would not be proof or ...

The mystery of gravity has captivated us for centuries. But what is gravity and how does it work? This engaging book delves into the bizarre and often counter-intuitive world of gravitational physics.

For centuries, gravity has been one of the most captivating and puzzling forces in the universe. Thanks to the groundbreaking ...
